The day before

On September 14, MYSZ opened at $1.73 and reached $2.52. The official close was $1.66. The last bar of that day in our data was $2.51, well above the close.

That morning at 8:15, PRNewsWire ran: “MySize Announces Acquisition-Led Strategy Focused on Defense Technology”.

Pre-market

The first trades on the 15th were at $2.47, already above the $1.66 close. The float is only 640,742 shares, so it doesn't take much volume to turn it over.

By 4:05 about 205,000 shares had traded, roughly a third of the float. The price was around $2.48.

From $2.38 at 4:03 it ran to $3.14 within the 4:05 minute, up 32%. By the end of the 4:07 minute, more shares had traded than exist in the whole float (640,742).

The run peaked at $3.31, the high so far, at 4:07 a.m. That was 99% above the previous close. It was already coming back by 4:08. At 4:08:52 a single sell order took 18,872 shares from $3.06 down to $3.00 across 7 price levels. By 4:09 the low was $2.76.

It tried once more. At 4:15 a.m. it reached $3.20, under the $3.31 top. From there it drifted down: $2.74 by 5:00, $2.54 at 6:19, and $2.45 at 7:01.

There were smaller bursts. At 5:31:25 a buy order swept 26,688 shares from $2.79 to $2.87 across 9 levels. At 7:03:17 another bought 19,931 shares from $2.53 to $2.57. At 7:59 a buy order took 40,559 shares from $2.51 to $2.61 across 11 levels, and a 20,754-share sell hit five seconds later. None got back near $3.31.

9.04 million shares traded before the bell, about 14 times the float.

The open and the wall at $3.08

It opened at $2.37, up 43% from the previous close and 28% under the pre-market high. At 9:30:00 a single print of 28,375 shares went through at $2.38. The first minute traded 152,245 shares and dipped to $2.21. A 19,631-share sell swept from $2.32 to $2.27 at 9:30:09.

From 9:34:25, someone was offering stock at exactly $3.08. It peaked at 41,884 shares at 9:38, about 6.5% of the float. The stock was trading near $2.40, so the wall sat far above it.

The 9:34 candle reached $2.53, the high of the first half hour after the open. The price never got near $3.08. At 9:51:56 the wall was pulled. Other ask walls sat above the price too. One at $3.49 stood from 5:31 a.m. and was pulled at 9:38. Another at $3.00 had been on the book since 6:12 a.m. The price had not reached either.

The rest of the morning

After the 9:34 high it slipped to $2.31 by 9:56.

It went lower. At 9:57:57 a sell order took 21,407 shares from $2.27 to $2.24. At 9:59:56 another sold 41,252 shares from $2.32 to $2.18 across 15 levels. The low of that flush was $2.18. By 10:01 it was back at $2.31, but it kept sliding, and at 10:15 it hit $2.07.

It then chopped near $2.15 for most of an hour. At 11:15 a buy order swept 27,205 shares from $2.17 to $2.23. At 11:40 it pushed to $2.60 on 100,699 shares in that one minute. It was back at $2.42 by 11:42.

Afternoon low and the close

From midday it drifted lower on thin volume. At 2:59 p.m. it hit $1.84, the low after the open, on 40,587 shares. It bounced to $2.16 by 3:05. The $3.00 ask wall from 6:12 a.m. was still there; it peaked at 42,473 shares at 3:52 p.m.

A late push in the 3:59 minute took it to $2.32. It closed at $2.31, 30% under the $3.31 high. That high came before the bell, 40% above the open.

The regular session traded 4.36 million shares. For the whole day, 13.74 million shares traded: the float changed hands about 21 times, at 42 times its normal volume.

After hours

After the close it traded up to $2.53 at 5:13 p.m. After-hours volume was 344,733 shares.

At 8:00 p.m. PRNewsWire ran: “MySize Announces $2.5 Million Private Placement Priced At-the-Market Under Nasdaq Rules”. The last bar in our data, at 7:59 p.m., was $2.38.

What to take from it

• The biggest move can be over before the open. The $3.31 high came at 4:07 a.m. By 9:30 the stock opened at $2.37, 28% lower.
• After the top, the next push stopped lower. $3.31 at 4:07 a.m., then $3.20 at 4:15 a.m. Later bursts at 7:03, 7:59 and 11:40 didn't get back near it.
• A big ask wall far above the price is not the same as a ceiling being tested. The $3.08 wall grew to 41,884 shares while the stock traded near $2.40, and it was pulled at 9:51:56 without the price ever reaching it.
